"To make gravy, heat oil and butter in large skillet on low heat. Add onion and cook 10 minutes, or until beginning to caramelize. Stir in flour and cook 2 to 3 minutes, stirring constantly until flour is golden. Add sugar, red wine vinegar and stock. Simmer until thickened, about 8 to 10 minutes. Season with salt and pepper.  Serve immediately with sausages and potatoes."
